Theory
vt = 10 sin (wt+0)
f= 50hz
I = v‾/z
Z = zl + zc
= xL=xC
ἰ wl-I / wc=(wl-I / wc)
Z = R+i(x)
Z‾= (wl-i/wc)
I= v‾/Z‾ = vm/√z

• “An LC circuit, also called a resonant circuit, tank
circuit , or tuned circuit, is an electric circuit
consisting of an inductor, represented by the letter
L, and capacitor, represented by the letter C,
connected together,”
• In case of capacitor voltage lag to current
• In case of inductor voltage lead to 90⁰

Application
• It is used in Lc oscillator to generate magnetic flux
b/w the coil.
• Lc circuit are used for generating signals at a
particular frequency or picking out a signal at a
particular frequency from a more complex signal.
• They are key components in many electronics
devices particularly radio equipment used in circuit
such as oscillators
